What problem does it solve?

This Skill helps identify the precise layer where numerical divergence occurs between FastVideo and the official reference implementation, facilitating targeted debugging.

Core Features & Use Cases

• Layer Divergence Detection: Instruments both models with hooks to detect the exact tensor boundary causing discrepancies.
• Root Cause Analysis: Assists engineers in pinpointing source code differences or implementation errors at the layer level.
• Use Case: When component parity tests fail and initial debugging methods are inconclusive, use this Skill to visualize layer-wise residuals and isolate the divergence.

Quick Start

Load this Skill during a parity failure and run the debug script with appropriate model loaders and inputs for detailed layer analysis.
